LUBRICATOR.

SPECIFICA TIGN forming-part of Letters Patent No. 779,609, dated January 10, 1905.

Application filed February 20, 1903. Serial No. 144,269. Y.

To all). whom it 1n/ty concern; y Be it known that we,PuTn-R HENRY KNIPPER and SIDNEY CHURCH MACKAYE, citizens of the United States, and residents of Rochester, in the county of Monroe and State of Newl Yorln. have invented certain new and useful Improvementsin Lubricators, of which the following is a-speciiicat'ion.

This invention relates' to lubricators of the To kind` wherein pumping devices are employed to automatically feed the lubricant from a reservoir to the parts to be lubricated. T1 The 'object of the invention isto provide an fiimproved lubricator capable of distributing' lubricants consisting ofsolid particles-such, for' instance, as a heavy oil and plumbagb-or other similar materials-#without clogging the pump-cylinder or any of its receiving or distributing connections.

'rdinarily lubricators are so constructed that the vpassages for the lubricant between the reservoir and the pumping devices are controlled by valves. So, also, are the passages for the, lubricantleading from the pumping devices to the parts to be lubricated. These valves 'are objectionable features in lubricators, particularly Where heavy lubricatingmaterials .of theabove-described character are employed. The valves have a tend- 3O ency to cholie or clog either in receiving the lubricant from the reservoir o1' distributing. it to the parts to be lubricated. In either instance the lubricator is rendered useless and the valves must be cleared before it can again be properly operated.

The present invention discloses a lu bricator that removes the above-named objections and facilitates the feeding of the lubricants to the desired parts in the simplest possible manner.

y in order that our invention maybe fully understood, We will proceed to describe it with referenceto the accompanying drawings, in which"H Figure 1 is a vertical sectional view on the line an, Fig. 2. Fig-2 is an elevation; and Fig. 3 a detail sectional view on the line?, Fig. 1.

in the drawings, l denotes the reservoir for the lubricant, having passages 2 at the bottom leading to the pump-cylinders. Leading from the pump-cylinders are branch pipes 4, unltlng with a common delivery pipe 5,

I through which the lubricant is fed to the parts to be lubricated. Reciprocating in the pumpcylinders 6 .are pistons or plungers 7, that 55 pass through the ordinary stufhng-boxes 8 in the top of the cylinders and are pivotally connected with connecting-rods 9, the upper ends of the connecting-rods having` pins 10, that slide 1n guide-blocks l1, secured to the 60 face of gears 12. The gears 12 are mounted on shafts 13, said shafts being journaled inlugs projecting f rom the Walls of the reservoir 1 and are driven by a gear l-l, located under and in engagement with said gears,the shaft 15,0arrying the gear 14e, being journaledin the reservoir 1. At the opposite -end of the shaft 15 is a Worm-Wheel 16, meshing With a Worm 17 on a shaft 18, connected in any suitable manner With a rotating' part of the engine or machine 70 to which the lubricator is tofbe attached.

The lower ends of the pump-cylinders 6 are of conical formation and are seated in the base 1 of the reservoir. The' cylinders are held in .their seats by means of threaded sleeves 20 75 engagii'ig the base 1', the bottoms of the sleeves abutting the annular projections 6 on the cylindcrs. The cylinders are designed to oscillate by means of intermediate mechanism connecting the cylinders with the shaft 15, com- 3C prising sector-pin ions 21, that encircle the cylinders just above the base 1/ and are held in position by means of set-screws 22. A rackbar 23 engagesV these pinions and intermittently oscillates the cylinders to open and 35 close the ports or passages to permit the oil to be pumped from the reservoir to the parts to be lubricated. The conical ends of the cylinders have ports di and 6l. The ports 62 are inlet-ports through which the oil is supplied to the cylinders, and the ports 63 are outletports through which the lubricant is distributed. The rack-bar has a pin-and-slot connection 24: 25 with a dependent arm 26, that is pivotally supported at 2T on a stud or post 95 projecting from the outer wall of the reservoir. The upper part of the arm 26 is bifur-Y cated and has mounted at each extremity of Y its tbifurcations suitable antifriction-rollers 31. During each' revolution of the gear 14 the rollers 31 are alternately'engaged. by a stud 35, 'carried'on the face of the gear-wheel- 14, Figr'2. This alternate engaging of the rollers 31 on the bifurcated arm 26. by the stud on gear 14 will cause the said arm 26 to .be oscillated, which in` turn, by reason of its connection. therewith, -will reciprocate the.

through themedium of the sector-pinions 2'1 secured thereto.

It willbe noticed that for each revolution of the shaft l5 the dependent arm 26 Will be shifted twice'-'-tha`t'is, the stud 35 (see Figs.-

2 and 3, which show the pistons in 'their extreme positiohs or about to begin a new stroke)` -will cause the arm 26 to move the rack-bar to the left, thereby oscillating the cylinders to open the. reservoir-portl .in one cylinder and close it in the other and open thc dischargingport in one cylinder and'clos'e it in the other. Whenever the pistons reach the extreme of '.rack-bar 23 and oscillatethe cylinders 6 their stroke in eitherydirection, the arm 26l willbe' oscillated by the above-described contact with the stud on gear 14, andthe -inlet and outlet ports of the cylinders will alternately; open and close to receive the lubricant from the reservoir andsupply it to 'the parts to be lubricated.

By. referring' to'Fig. l it can be clearly ob-l .served that the voscillation of the cylinder acts efectually as a valve" t'o .open and close the ports, but allows the vpassages and` ports to he made large enough rto permit the use o'f heavy oils, plumbago, 'or similar lubricating material ,Without any clogging action in the cylinders.

1t will be seen that the'iiow oflubricant will be practicallyconstant throughthe supplypipe 5 by the alternate supply ofvoil. from the branch pipes 4, leading from the' cylinders.

The operation of the apparatus is as fo l lows: Inthepositionshown in Fig. Il' one ofthe pistonsis at its/extreme upward stroke,

while the other is at its extreme lower stroke,

and the stud on the gear 14 is in-position to operate the bifurcated arm to move the rack bar and through the -mediumof the pinions oscillate the' cylinders to openand close the alternate ports to accommodate the action of ,fthe pistons in controllingv the iiow of the lu..

bricant into and out of the cylinders;

Fig.' 3 clearly shows the relation of' the ports tothe suppl,T and exhaust passages and also' each other.
